I have an MG6200 that got the same message "There are ports that cannot be used..." I switched to wired and reset printer to LAN, no luck. I switched to wireless and set up that. No luck. I set back to wired, and went to DOS PROMPT and pinged the IP address from the wired lan. Then the printer started printing happily away. I think there's a problem with the proprietary IP communication that Canon is using.

I have the same problem ... MX892 ... Belkin router ... No problems with any of my other computing devices staying connected to wifi.
After the Canon goes to sleep, I can never print to it as the printer is never found.
I have to go to the printer every time and re-find the router.
Please help. Very frustrating and a productivity killer.

Just to confirm, other machines on prem are Windows-based. We don't print from them, but I just did a test and they can't print to the Canon MX892 after it has gone to sleep, either.
The printer continuously needs a forced connection to wifi.

Interestingly (to me, at least), I just scanned a document and the computer found the scanner with no problem.
I then went to print and the computer couldn't find the printer. I connected the printer to wifi again via the menu setting on the printer and was able to print.
So the computer found the scanner without problem but could not then immediately print to the same device until I used the menu setting on the printer to connect to wifi.

On 2014-10-06 I posted the details of the solution that worked for me at a similar Canon forum:
It continues to work for me. The wireless printer connection hasn't failed since then.
It's a permanent solution that you only need to do once. (It isn't a workaround that wakes the printer temporarily after its connection fails.)
The solution involves using your computer's web browser software to access the printer's built-in web server (by entering the printer's IPv4 address into the web browser's address field), going to the printer's Settings webpage, and entering a value in the Location property. (Which was blank by default.)
If you try it, please post (preferably in that other Canon forum) a few days afterward, to report whether it solved the problem.

My MX892 worked fine for a few months, but it now seems to "forget" its connection to our local network after every use. This means that we have to manually key in the password to the network every time we print for it to work. Otherwise, we get the "printer not connected" or "printer not reponding" messages.
What's the deal? Is there a fix for this?
